Healing Progression Of The Free Gingival Graft
Write short note on fate of free gingival autograft.
Answer. Extent to which the connective tissue withstands the transfer to new location determines the fate of free gingival autograft.
Maintenance of graft is initially by diffusion of fluid from the host bed, adjacent gingiva as well as alveolar mucosa.
Fluid is a transudate from host vessels which serve nutrition and hydration which is necessary for initial survival of the transplanted tissues.
On the very first day connective tissue become edematous and disorganized as well as it undergoes degeneration and lysis of some of its elements. As healing commences edema is resolved and degenerated connective tissue is replaced by the formed new granulation tissue.
Revascularization of graft starts at second or third day.
Many of graft vessels degenerate and are replaced by new ones. Central part of surface is last to vascularize and this is completed at the tenth day.
Necrosed and degenerated epithelium is replaced by new epithelium from borders of recipient site.
